How does tooth decay affect my body?

The first way is that tooth decay, if left alone, will eventually cause a cavity. This is almost always the starting point. And hopefully, it ends there (e.g.: taking care of the cavity with a filling). But if the cavity is not handled and the tooth decays further, the tooth could weaken and break, and/or an infection/abscess could form. The infection could then spread, causing a myriad of health complications (too many to list here). So the common equation becomes tooth decay leads to cavities which leads to infection which leads to… well, at that point, you really need to see your dentist.

Tooth decay itself can have a minimal effect on the body. However, as you lose teeth due to the non-restorable situations by decays, your ability to chew can dramatically decrease. When you cannot chew properly, you usually swallow the food without making it small enough for the stomach to digest. Then, there is an upset in your stomach that it can lead to GERD which is Gastroesophageal reflux disease.

Also, toothache is one of the worst pains you can have. Having the constant toothache, it can dramatically lower the quality of your life (can cause stress/chronic pain/depression).  
Tooth decay does more than affect your smile. When you have untreated tooth decay in your mouth it can lead to a toothache, gum disease, and eventually, tooth loss. When your mouth hurts, you can't smile or speak or chew properly. That's why regular dental appointments are so important. And always remember to brush your teeth twice a day for two minutes with a fluoride toothpaste, and to floss regularly.

Tooth decay can affect your body. At first your tooth may be sensitive and you may avoid eating certain foods which would affect your nutrition. Left untreated the decay can cause pain in the tooth leading to a loss of concentration and loss of sleep at night which can affect your performance at work and at school. The decay can also cause the tooth to abscess leading to an infection. The infection can spread throughout your body causing flu like symptoms. The infection can also necessitate the need for the tooth to be extracted and maybe the surrounding teeth. In rare instance, the infection can spread to the brain causing death. Regular visits to the dentist are important to diagnose and treat tooth decay.
